| Reviving a B&W G3 |
Posted by: silvercreekvalley on 2016-11-13 07:18:08
Trying to revive a B&W 350MHz G3 mac I picked up yesterday.
So first thing is - it appears to be complete - howevever I have some booting issues.
1) Pressing power on starts the Mac, the disks etc startup. I see a couple of green lights on the PCB so power is OK.
2) I get the Mac chime, followed by a short blast of white noise.
3) There is then no video output
I've tried the usual, removed the battery, reset firmware, disconnected the disk drive, reseated the video card and memory and all looks OK.
Any ideas - or am I looking at a new motheboard/video card?
Thanks

Did you press the cuda button?

If a CUDA reset doesn't help, I'd try removing and reseating the video card.

Thanks for the help - yes I tried pressing the CUDA button. Also removed and reseated the video card a few times.
Nothing at all from the video card - tried a few different monitors just in case.
Looks like I might need a new motherboard ?

Which video card is installed? Somebody might have just stuck a PC card in and they don't work. Also try using just 1 stick of PC100 RAM you know is good.

Now I have a ATI Radeon 9200 Mac Edition 128MB PCI

Sounds like bad RAM or a bad socket. Try it with a known good (or a couple different sticks one at a time) stick of RAM and try different slots.
